Description

(54) SEPARATOR

I

The invention relates to a technique for separating liquids from gas-liquid mixture flows moving in pipes, and is intended primarily for the preliminary purification of gas-liquid emissions from closed fermenters in which deep-seated cultivation of aerobic microorganisms is carried out.

Known separator, comprising a housing with inlet and outlet nozzles located in the upper part of the housing and the grille placed in the lower part of the housing 1.

Coming out of the nozzle, the flow hits the grate, the liquid passes through the grate and flows to the bottom of the chamber. The separated gas rises to the top and is removed through an opening in the upper part of the chamber. The crib is designed to reduce secondary spreading.

A disadvantage of the known separator is that it is impossible to use the inertial-shock principle of separation. The presence of a grating, which does not actually carry a functional load, complicates the manufacture and cleaning of the separator.

The closest to the described invention to the technical essence and the achieved result is a separator for separating liquid from gas-liquid mixture, including a housing with an inlet pipe and an outlet pipe located in the upper part of the housing, a pipe for removing liquid 2.

A disadvantage of the known separator is that during the movement of the gas-liquid mixture in the inlet nozzle, a part of the liquid is deposited on the pipe walls and moves along it in the same direction as the entire flow; this part of the liquid is largely sprayed by the flow of the gas-liquid mixture during the entry

it from the pipe into the separator, which reduces the efficiency of separation. In addition, if the gas in the separator is under pressure, part of it can flow into the nozzle to remove the separated liquid, and from there into the room.

In order to improve gas cleaning efficiency in the proposed separator, the inlet is angled to the axis of the housing, and its lower end is provided with a chute ...: The angle between the inlet and the housing is 10-20 °, and the lower end of the inlet is located at a distance from the wall of the case, equal to 0.2-0.4 of the diameter of the case. The chute is made of a semi-circular section with a diameter equal to the diameter of the inlet nozzle, the lower end of the chute is located at a distance from the wall of the housing equal to 0.05-0.1 of the diameter of the housing. The inlet pipe has a length greater than 2-4 times the height of the body .. The separator is equipped with a float valve located in the lower part of the body. The drawing shows the proposed separator, a longitudinal section. The separator includes a vertical cylindrical body 1 with an inlet 2 for supplying the gas-liquid mixture to the chamber. The height of the case I refers to the diameter as (3-5): By the length of the nozzle 2 exceeds the height of the case by a factor, and its axis forms an angle of 10-20 ° with the axis of the case. The lower end of the nozzle is separated from the side wall of the housing at a distance equal to 0.2-0.4 of the diameter of the housing. The bottom end of the nozzle enters the groove 3, the semicircular section; whose diameter is equal to the diameter of the nozzle, and the axis coincides with the axis of the latter. The concave side of the groove faces upward, and the lower end does not reach the side wall a distance equal to 0.05-0.1 of the internal diameter of the cross-section of the housing. Inside the separator, there is a float valve 4. To ensure that the float does not turn over, a load 5 is fixed in its lower part. The housing has a port 6 for removing the separated liquid, an outlet 7 for removing the separated gas, and hatches 8 and 9 for cleaning and repair . The separator works as follows. Due to the fact that nozzle 2 is angled to the wall of the body, the flow of gas-liquid mixture entering the body is not just directed downward, but, following this direction, hits the side wall, is reflected from it under the sharp yrjfoMTrffpSflOin follow way down. A large part of the liquid droplets in the flow hits the wall, sticks to it and flows along the wall to the bottom of the chamber. A portion of the liquid droplets that hit the wall is sprayed. Splashes, together with those droplets that did not hit the walls as a result of the turbulence of the flow, are carried along by the flow of reflected gas downwards. In the lower part of the body, the droplets settle to the bottom under the influence of inertia and gravity, and the gas turns up and leaves the chamber through the nozzle 7.

Claims (3)

703122 The separation of liquid from gas in the lower part of the chamber is due, among other factors, to a decrease in the linear flow rate as a result of an increase in its cross section. That part of the liquid phase of the gas-liquid mixture, which moves along the walls of the nozzle, thanks to its inclined arrangement accumulates in the lower part of the transverse profile of the nozzle channel. Upon exiting the nozzle, this part of the liquid does not splash out, but flows smoothly along the chute into the lower part of the body, where the gas velocity is low and there are no conditions for splashing. In the event that there is a liquid in the chamber, the valve floats and does not prevent the liquid from being removed through the nozzle 6. When there is no liquid, the valve is lowered and prevents gas from entering the system to treat the removed liquid. The oblique arrangement of the gas-liquid mixture inlet and the presence of a gutter reduce secondary spraying and splashing. An automatic float valve prevents the ingress of gas into the separation system. All this, as well as the combined use of the inertial-shock and gravitational separation principles, increases the efficiency of the separation of the liquid by the separator compared to the prototype by 45-51 / 0. The use of the separator wall as a baffle plate and the absence of complex devices inside the separator simplifies its manufacture, unlike analogs, reduces the flow resistance and facilitates cleaning of the separator, which is especially important when used in the microbiological industry.
